    摘要： An integrated electro-optic frequency comb generator based on ultralow loss integrated, e.g. thin-film lithium niobate, platform, which enables low power consumption comb generation spanning over a wider range of optical frequencies. The comb generator includes an intensity modulator, and at least one phase modulator, which provides a powerful technique to generate a broad high power comb, without using an optical resonator. A compact integrated electro-optic modulator based frequency comb generator, provides the benefits of integrated, e.g. lithium niobate, platform including low waveguide loss, high electro-optic modulation efficiency, small bending radius and flexible microwave design.

    摘要： An optical device includes a substrate, an oxide layer on the substrate and an electro-optic device on the oxide layer. The oxide layer is at least one micrometer thick. The electro-optic device includes an electro-optic material having a thickness of not more than one micrometer. The silicon substrate, oxide layer, and the electro-optic material terminate at an edge. At least one of the silicon substrate has a thickness of at least five hundred micrometers or the edge includes a recessed region corresponding to a portion of the oxide layer.

    摘要： An optical device is described. The optical device includes a waveguide, a first engineered electrode, and a second engineered electrode. The waveguide includes at optical material(s) having an electro-optic effect. The optical material(s) include lithium. A portion of the waveguide has a waveguide width. The first engineered electrode includes a first channel region and first extensions protruding from the first channel region. The first extensions are closer to the portion of the waveguide than the first channel region is. The second engineered electrode includes a second channel region and second extensions protruding from the second channel region. The second extensions are closer to the portion of the waveguide than the second channel region is. A first extension of the first extensions is a distance from a second extension of the second \extensions. The distance is less than the waveguide width.

    摘要： An optical modulator that uses adiabatic tapers to change the width of the waveguides between multimode waveguides and single mode waveguides on a low-loss, e.g. thin-film lithium niobate, electro-optic platform. The architecture enables the utilization of the fundamental mode of multimode wide optical waveguides that have lower optical propagation loss without sacrificing the benefit of the signal integrity and ease of control of single mode operation.

    摘要： An interface for an optical modulator and the optical modulator are described. The interface includes first and second differential line pairs. The first differential line pair has a first negative line and a first positive line arranged on opposing sides of a first waveguide. The first negative line is on a distal side of the first waveguide relative to a second waveguide. The first positive line is on a proximal side of the first waveguide relative to the second waveguide. The second differential line pair has a second negative line and a second positive line arranged on opposing sides of the second waveguide. The second negative line is on a distal side of the second waveguide relative to the first waveguide. The second positive line is on a proximal side of the second waveguide relative to the first waveguide. The first and second waveguides each include lithium niobate and/or lithium tantalate.
